IMPROVEMENT IN TURNING WAGON-HUBS.

TO ALL WHOM IT MAY CONCERN:

Beit known that I, WALLACE W. CLEAVELAND, in the city of Coldwater, Branch county, in the State of Michigan, have invented certain new and useful Improvements in a. Machine for'lurning, Shaping, and Gauging Wagon-Hubs for all kinds of wheeled vehicles; and the follewing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents a plan or top view of the machine. l

Figure 2 shows an end elevation of the same.

The object of my invention is to make hubs, for all wheeled vehicles, vof more uniform shape and size, and much faster than they canlbe turned. in a lathe, as they have heretofore been done. l

vMy invention consists in the construction, arrangement, and combination of the revolving cutter-head, the adjustable sliding frames, and the lathe. A

To enable others to make and use my Aimproved. hub-making machine, I will proceed to describe it more in detail, referring to th'e drawings, and to the letters marked thereon.

I make a strong frame, A' A, of metal, or other suitable material, with feet orV straps, B B, for securing it c to the bench. On the top of the frame A A, extending crossways from the back, A', to the lathe-shears C C, I

secure another frame, D, with elevated ways, d cl, on which the elevated frame E slides forward and. hack by the action of'the screw F, turned by the crank-handle Gr in front of the machine.

The uprights of the frame E are provided with journal-boxes, e e, in which the shaft f is hung, on which the revolving cutter-head H is secured, the same being provided with a double series of adjustable blades, bits,`

andA saws, so arranged and adjusted as to, reduce the wood, and give the required length, shape, and size of the hub, the various sizes being determined by a scale or stop,.b, on the way d.

The front of the machine is made like an'ord'inary lathe, with-,head Iiand mandreliJ', on which is a spiralV cog-wheel, L, turned by a worm-pinion, c, on the shaftl Z, by the pulley L, which has a clutch, operated by the hand-lever K, to start or stop the revolving mandrel J, yto which the mandrel M connects, on which the hub O is driven to be turned or shaped. The other' end of the mandrel M is held by a pivot in the tail-screw N, the i.

same as any ordinary lathe. l

The blocks being cut a suitable length, and bored through, (the size of the mandrel M, which is driven in,) they are then placed in the lathe, the cutter-head adjusted to the proper place bythe crank-handle I and screw Q, the cutters put in motion by abelt on the long pulley R, on the end of the shaft f. It isthen brought up to the stop b, cutting its way into the block', when the block is set slowly revolving by a belt on the pulley L, and turned once round, andthe hub O is completed.

By a machine constructed to operate as above described, atleast' four hubs can be made a'nd completed, exactly the same form and size, while one can be turned'by the most skilful turner, and no skill is necessary vfurther than to put the blocks inthe lathe and adjust to it, and start the machine.

I do not claim, broadly, revolving cutters for reducing or shaping turned work, as that' device is old and common property; but I l What I do claimasmy invention, and desire to secure by Letters Patent, is A The arrangement of the revolving cutter-head, carried in the lateral and longitudinal-moving frame, with the fixed arbor for revolving the block of which the hub is made, all as herein described;
